This July 2014, I flew to Paris from San Francisco with my son. For the return flight, we paid $94 ($188 total) extra for advance seating for what Air France calls "Siege Plus". We were to be seated by an exiton the upper deck of an A380 allowing us all the leg room we wanted.
When I did the online check-in, I realized the seats had been changed to regular seats.
We arrived at the airport 2 1/2 hours ahead of our early departure hoping to straighten out the problem and to have breakfast before flight time.
We were sent from one Air France counter to the other, all the way to the boarding gate counter. All that for nothing! Air France was unable to get our paid seats back and refused to upgrade us to better seats.
Air France ignored my first email to them and ended-up reimbursing the fee and gave us 5000 points on our Skymiles accounts. Laughable!
What is the point of paying for a seat if it is not guaranteed?
The cabin crew on Air France have always been tops but the rest of the company, and the constant threat of strikes make this a low rate company.
